Gas ring on hob

[BusyBuilder]

Lights okay but goes out as soon as you let go. Flame is as bright and powerful as other 2. Cant see anything wrong with it. But I'm no expert. Any ideas ?

Pull the knob out a bit and try again - oohh err

Sounds a similar prob to this one from Saturday (e.g. a faulty or badly set thermocouple).

Dirty burners?

The gas hob works fine. The gas oven works fine. The grill lights, but goes out when you let go of the button, however long you leave it. What would cause this? Is it likely that only the grill burners need cleaning? I've no idea what other causes there might be.

You'll need to learn about thermocouples - the device that sits in the flame and when hot holds gas open, if it gets cool (like flame blown out etc...) it's job is to shut off the gas. Clever and very simple widget.

Another for thermo-couple.
When it's hot it holds the valve open.... If its faulty, or out of the flame, it can't hold the valve open.

Just had this on one burner of a Smev hob. The FFD thermocouple required a push towards the burner. It wasn't visibly out of position and moved a tiny amount - but it solved the problem permanently. They're 'held' in place by a spire nut and an inconsiderate wipe with a dishcloth is all it takes.

Thanks all, Tonyidle was spot on, all working now.
